INVENTOR. GEORGE E. THOMAS ATTORNEY FIQ4 United States Patent 3,082,958 LAWN SPKLER George E. Thomas, 4404 Walnut St, Chino, Calif. Filed Mar. 23, 1962, Ser. No. 181,881 2 Claims. (Cl. 239-234) This invention relates to a lawn sprinkler for the purpose of distributing water on a lawn, golf course, garden, or .the like.

An object of my invention is to provide a lawn sprinkler which includes a jet nozzle through which water flows against a disk. The disk, when rotated by the jet, will impart a rotary motion to the jet nozzle to distribute Water over the surface of the lawn, or the like. In connection with the jet nozzle an adjustable valve is provided to control the flow of water through the nozzle.

Another object of my invention is to provide a novel lavm sprinkler in which the user can entirely shut 011 the flow of water to the jet nozzle in order to move the sprinkler from place to place, and can permit normal flow of water to the jet nozzle as soon as the sprinkler is repositioned.

Still another object of my invention is to provide a novel lawn sprinkler which is simple in construction, effective in operation, and inexpensive to manufacture.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing:

FIGURE 1 is a top plan view of my lawn sprinkler.

FIGURE 2 is an end view of the same.

FIGURE 3 is an enlarged sectional view taken on line 3-3 of FIGURE 1.

FIGURE 4 is a fragmentary vertical sectional view of the upper control valve.

Referring more particularly to the drawing, the numeral 1 indicaes a sled-like base, which is preferably formed of metal and which includes a pair of horizontally spaced skids 2-'3 upon which the sprinkler rests. A hose fitting 4 is fixedly mounted at the center of the base 1 and the garden hose (not shown) is attached to the threaded end 5 of the fitting 4. A sleeve 6 extends vertically into the fitting 4, preferably by threading the sleeve into the fitting substantially as shown. The purpose of this fitting will be subsequently described. A valve button 7 screws into the bottom of the fitting 4 in vertical alignment with the sleeve 6, and the purpose of this valve is to completely shut off the water when the user wishes to move the sprinkler from place to place, as will be subsequently described. A valve packing or seat 8 is mounted on the upper end of the button 7 and is in use when a complete water shut-off is desired. A pipe 9 extends into the sleeve 6 and is both rotatable in the sleeve, as well as having a limited longitudinal movement which is required when a water shut-off is desired, and is accomplished by engaging the packing 8 with the bottom of the pipe 9. A head 10, on the bottom of the pipe 9, serves as a limiting shoulder to prevent the pipe 9 from being forced out of the fitting 4. Water pressure from the hose will push the pipe 9 upwardly and will permit free flow of water upwardly from said pipe.

A plate 11 is fixedly mounted on the upper end of the pipe 9 in the following manner: A valve body 12 is attached to the bottom of the plate 11 by means of a screw 13, or other suitable attaching means. The pipe 9 is suitably attached to the valve body 12 by soldering, welding, or other suitable means. The valve body 12 is formed with a fluid passage 14 and the nozzle pipe 15 extends into this passage and is suitably secured to the body 12 of the valve. A jet nozzle 16 is mounted on the outer end of the pipe 15 and the jet nozzle is positioned 3,82,953 Patented Mar. 26, 1953 below and adjacent to a disk 17, which is journaled on the underside of the plate 11 and adjacent one end of the plate. The disk 17 is toothed on its lower surface and is also eccentrically weighted so that as the disk rotates a horizontal force is exerted on the plate 11, due to this eccentric weighting, and this horizontal force will rotate the plate slowly around the center line of the pipe 9. The disk 17 also causes a spray-like action to occur as the water flows from the nozzle 16, and also tends to distribute water immediately adjacent to the base 1 of the sprinkler.

To limit the flow of water through the pipe and 4 the nozzle 16, I provide a valve within the valve body 12, which consists of a tube 18 which screws into the valve body 12 and through an appropriate hole in the plate 11. A core 19 is journaled within the tube 18 and a control handle 20 is fixedly attached to this core. Thus rotation of the handle 20 will cause the tube 18 and the core 19 to also rotate for purposes of flow adjustment into the pipe 15. The core 19 is formed with a horizontal bore 21 which is aligned with the port 14, and a vertical bore 22 which is aligned with the pipe 9. Thus rotation of the handle 20 will move the bore 21 into or out of alignment with the port 14 to control the flow of water into the pipe 15. The tube 18 is provided with outlet holes 23 therein, which are aligned with or misaligned with the bore 21 for the purpose of controlling water flow.

To limit the rotating movement of the circular handle 20, I provide a stop pin 24 which rises from the plate 11 and extends into an arcuate slot 25 in the circular handle 20.

In Operation The user controls the flow of water flowing from the jet '16 by rotating the handle 20 and thus controlling the core 19 and the bores therein, so that the sprinkler will cover a desired area. If it is desired to move the sprinkler while the water is still flowing from the nozzle 16, this can be done by pressing downwardly on the plate 11, which pushes the pipe 9 downwardly into engagement with the packing 8, thus completely shutting oif the flow of water and permitting the user to reset the sprinkler, after which the plate 11 is released and the sprinkling action continues.

Having described my invention, I claim:

1. A lawn sprinkler comprising a base,

a hose fitting mounted on said base,

a vertical pipe extending from said fitting and rotatably journaled therein and having a limited vertical sliding movement in the fitting,

a valve body mounted on said pipe,

a jet nozzle projecting from the valve body,

a horizontal plate fixedly mounted on the valve body,

a driving disk rotatably mounted on said plate and positioned adjacent the outer end of the jet nozzle,

and a shut-off valve means on said pipe to cut off water flow to the jet nozzle,

said shut-01f valve comprising a valve packing in said fitting, the end of the pipe within the fitting engaging the packing on vertical movement of the pipe to shut-ofi water flow into the pipe.

2. A lawn sprinkler comprising a base,

a hose fitting mounted on said base,

a vertical pipe extending from said fitting and rotatably journaled therein and having a limited vertical sliding movement in the fitting,
